Ceramic saddle rings are ceramic random packing materials primarily composed of silicon dioxide (SiO₂) and aluminum oxide (Al₂O₃), manufactured through high-temperature sintering. They exhibit properties such as resistance to strong acids, high-temperature tolerance, and high compressive strength (acid resistance ≥99.9%, alkali resistance ≥88%, compressive strength ≥10 N/mm²). Designed as an improvement over traditional saddle rings, they feature serrated or corrugated protrusions on smooth curved sides and added perforations on the saddle back, optimizing fluid pathways to significantly enhance mass transfer efficiency and reduce pressure drop. The surface of ceramic saddle rings incorporates a serrated/corrugated design and integrated curved channels, which increase gas-liquid contact area, reduce flow dead zones, and improve mass transfer efficiency by guiding gas along curved paths and minimizing liquid wall flow. Internal perforations further promote multidirectional gas and liqui...

A cyclone is a device that uses centrifugal force to separate solid particles or droplets in a mixture from the fluid. It is widely used in industries such as mining, metallurgy, coal, power, and chemical engineering. During operation, the equipment rotates at high speed, and the mixture inside will cause extremely severe impact and wear on the internal components (especially the feed inlet, cone, and sand discharge port, etc.). This wear will shorten the equipment's lifespan, reduce the classification efficiency, and increase operating costs. Therefore, wear-resistant ceramics emerged. They have excellent anti-wear and anti-shock properties, with a Mohs hardness of 9 and a smooth surface that is not prone to adhering to materials.  Wear-resistant ceramics are usually applied in the form of liners or inserts to the most vulnerable areas of the cyclone:  1.Feed inlet Function: The part where the slurry first impacts at the highest speed and pressure, and where the wear is the ...

With its unique material properties, 99% alumina ceramic demonstrates considerable application potential in the field of bulletproofing, and has become an important choice among lightweight bulletproof solutions. 99% alumina ceramic possesses extremely high hardness and compressive strength. Its alumina purity is very high, and the density is extremely high. There are almost no pores or impurities inside. The hardness can reach above HRA90, and the compressive strength exceeds 3000 MPa. When a bullet impacts at high speed, the hard ceramic surface can instantly compress, deform, or even break the bullet head. At the same time, the high-density ceramic crystal structure can quickly disperse the impact force and consume the bullet's kinetic energy, preventing the bullet head from penetrating the bulletproof plate, thus providing time for the subsequent buffer layer to absorb the energy. In terms of lightweight design, 99% alumina ceramics have significant advantages. Compared with tr...

In the field of industrial wear-resistant materials, alumina ceramics hold a significant position due to their excellent wear resistance. This performance is not accidental; it is the result of the combined effect of a series of unique material properties. From the microstructure to the macroscopic properties, each characteristic provides a solid foundation for its wear resistance. High hardness is the core foundation of the wear resistance of alumina ceramics. The Mohs hardness of alumina ceramics reaches up to level 9, which is only second to diamond (level 10) and cubic boron nitride. It is much higher than that of ordinary metal materials (such as the Mohs hardness of steel is only 4-5 levels). In friction or impact scenarios, high hardness means that the material surface is less likely to be scratched or crushed. When hard particles or objects come into contact with the surface of alumina ceramics, the ceramic surface can resist deformation by virtue of its high hardness, reducin...

The main reasons for grinding flanges and pipe ends during the installation of wear-resistant ceramic pipes are as follows: 1. Ensure sealing Flange grinding: Flanges are key components that connect pipes, equipment, valves and other components in the pipeline system, and their sealing performance is crucial. Grinding the flange surface can remove burrs, dirt and oxide layers on its surface, thereby ensuring that the flange surface and gasket can fit tightly to form an effective seal. This helps prevent medium leakage and ensures the safe and stable operation of the pipeline system.   Pipe end grinding: Similarly, grinding the pipe end can remove unevenness and impurities on its end face, ensuring a tight fit between the pipe end and the flange or other pipe connectors. This helps reduce the risk of leakage and improve the overall sealing performance of the pipeline system.   2. Improve connection strength Flange connection strength: By grinding the flange surface, the contac...

1. The fixing method of bolt column type chemshun  wear-resistant ceramic lining is to connect with the bolt column. The height of the countersunk hole at the head of the bolt column is generally half of the thickness of the ceramic lining. Therefore, when the wear-resistant ceramic lining is worn to half, the bolt can no longer play a downward fixing role, and only the adhesive force of the glue is working. 2. The fixing method of welded wear-resistant ceramic plate is to fix it by gluing and iron bowl welding. As long as the iron bowl is not worn off, the welded wear-resistant ceramic plate still plays a downward fixing role. There is still a dual fixing effect of iron bowl and gluing. Construction method comparison:   1. The fixing method of bolt column type wear-resistant ceramic plate is to connect with gluing and bolt column. Construction process: drilling steel plate, applying glue, and fixing bolts. The disadvantage is that the steel plate needs to be drilled manually...
